IMPROVEMENT IN SUCKER-ROD JOINTS.

Specification forming part of Letters Patent No. 127,464, dated J une 4, 1872.

Specification describing a new and Improved Sucker-RodJoint, invented byADDISON CROS- BY, of VVestfield, in the county of Chautauqua and State of New York.

Figs. 1 and 2 are longitudinal sections at right angles to each other of my improved sucker-rod joint. Fig. 3 is a transverse section of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to a new means of fastening the ends of wooden rods in the metallic sockets that connect the same for use 'on pumps and other machinery; and consists sockets B by means of wedges O G, that are driven transversely through them, as shown. The slots in the metallic tubes B, for the admission of the wedges, are so much larger than the wedges, as indicated in Fig. 3, as to permit the wedges to be driven in far enough for producing the requisite enlargement of the wood in the tube. The rods are thus secure- 1y fastened, there being by preference two wedges at right angles to each other at each end of every rod.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination of the rod A, tube B, and wedge G, in such manner that the slot in the tube for the admission of the wedge is larger than the wedge, to permit therequisite spreading of the wood, as set forth. v

ADDISON CROSBY.
